Stimulant medication and reading performance: follow-up on sustained dose in ADHD boys with and without conduct disorders.

The study examined the sustained effects of methylphenidate on reading performance in a sample of 42 boys, aged 8 to 11, with attention deficit-hyperactivity disorder (ADHD). Two subgroups were formed based on the presence or absence of co-occurring conduct disorders. Subjects were selected on the basis of their positive response to methylphenidate as determined in a series of original medication trials (Forness, Cantwell, Swanson, Hanna, & Youpa, 1991). For the purpose of this study, subjects were placed on their optimal dose of medication for a 6-week period and then tested on measures of oral reading and reading comprehension equivalent to those used in the original trials, retested after a week without medication (placebo), then tested again the following week after return to medication. Only the subgroup with conduct disorders responded, and this response was limited to reading comprehension improvement in only those subjects who also demonstrated improvement in oral reading on original trials. No response differences were found between subjects with or without learning disabilities.     

A new chemotherapeutic investigation: Piracetam effects on dyslexia

Piracetam, a new drug which is thought to enhance learning and memory consolidation, was given in a 3300 mg daily dose to half of a group of fifty-five (55) dyslexic boys aged eight to thirteen years in a twelve week, double-blind, placebo controlled study. All subjects met stringent criteria, including: normal intelligence, normal educational opportunities, no severe emotional problems, no neurological handicaps, good physical health, not taking other psychotropic medication, and scoring at least 1 1/2 years below their mental age equivalent on the Gilmore Oral Reading Test. The children’s perceptual, language, and memory skills were examined and their reading, spelling, and writing abilities were measured using standardized instruments. Compared to the placebo control group, individuals treated with Piracetam showed statistically significant improvements above their baseline scores on measures of effective reading accuracy and comprehension, reading speed, and writing accuracy. The medication was extremely well tolerated, and all medical examinations showed no untoward effects. These results encourage further study of Piracetam’s potential as an adjunct for the clinical remediation of dyslexia.     

The Relationship of Spelling Recognition, RAN, and Phonological Awareness to Reading Skills in Older Poor Readers and Younger Reading-Matched Controls

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.     

Effects of Methylphenidate on Academic Achievement from First to Second Grade

The objectives of the current study were to identify the long‐term effects of Methylphenidate (Ritalin) on cognitive ability and academic achievement. A retrospective/longitudinal design was utilised in the study with dependent measures being scores from the Iowa Tests of Basic Skills (ITBS). The study included 17 experimental subjects who were identified with ADHD and placed on Methylphenidate between first and second grade. For each experimental child, a control child without ADHD was matched based on gender, Verbal IQ score, and family structure. Results of the study revealed that the Methylphenidate group's achievement was lower both before and after medication even after being matched on verbal abilities. The results also indicated that after receiving medication the Methylphenidate group's rate of learning was similar to the Control groups on Reading, Word Analysis, Listening, Vocabulary, and overall achievement. Finally, a positive relationship between dosage level and Listening subtest scores was observed while a negative relationship was obtained between dosage level and Vocabulary subtest scores.     

Follow-up of children with early expressive phonology disorders

Fifty-two children identified at age 4 to 6 years as demonstrating a moderate to severe expressive phonology disorder were followed to the third and fourth grades. Children were classified into two groups based on the presence of an early phonology disorder in isolation (P) or the presence of a phonology disorder with other language problems (PL). At follow-up, articulation measures failed to differentiate the groups; however, the PL group performed more poorly than the P group on measures of phoneme awareness, language, reading decoding, reading comprehension, and spelling. The P group demonstrated poor spelling skills relative to their reading and language abilities, suggesting residual spelling weaknesses in these children. The PL group reported more nuclear family members with speech-language disorders and with reading disorders than the P group. Findings support previous research linking early language disorders with later reading difficulties.     

Reciprocal Teaching of Comprehension‐fostering and Comprehension‐monitoring Activities with Ten Primary School Girls

Abstract This paper reports an experimental evaluation of a direct instruction procedure in which children are taught and practise activities to both foster and monitor their comprehension while reading. Three different class groups of low comprehenders, Standard 4, Form 1 and Form 2, were serially exposed to 21 days of 20‐25 minutes instruction in four study activities: summarising, questioning, clarifying and predicting. Instruction was by reciprocal teaching whereby the adult tutor and children took turns leading a dialogue centred around the important topics of the instructional text. The design of this study incorporated both with‐subjects multiple baseline and between‐subjects comparisons, the no treatment comparison groups being average and above average comprehending class peers. Daily comprehension assessment on a different text at the same difficulty level as that used for reciprocal teaching and pre and post intervention scores on a reading comprehension test served as the dependent measures for the study. Results show significant increases in accuracy on comprehension tests for all experimental groups upon introduction of the reciprocal teaching procedure. On completion of the intervention two of these groups scores matched those of the above average controls. Follow‐up probes eight weeks later showed that all groups had maintained their comprehension gains.     

Attention deficit disorder and specific reading disability: separate but often overlapping disorders

Within a large (N = 182) heterogeneous sample of clinic-referred children with DSM-III-diagnosed attention deficit disorder (ADD), three behavioral subgroups were identified via cluster analysis of teacher ratings: 40% of the children had ADD with hyperactivity (ADDH), 30% had ADD with hyperactivity and aggressivity (ADDHA), and 31% had ADD without hyperactivity or aggressivity. Proportionally more girls were in the ADD-only subgroup. Over half the sample (n = 94) were poor readers, with 82 meeting discrepancy criteria for specific reading disability (RD). Proportionately more boys than girls met the RD criteria (9.2:1.0), whereas the sex ratio of males to females for the whole sample was 5.1 to 1.0. Focusing just on white males, the three behavioral subgroups were significantly different on convergent validity measures, such as other teacher ratings, parent ratings, and interview-elicited ratings of externalizing behavior, but were not different on such divergent validity measures as IQ and achievement scores, self-ratings, and laboratory performance tasks. Boys in the ADD sample who did not meet criteria for RD had significantly higher IQs than those who did, but subgroups with and without RD still differed significantly on WRAT-R reading and spelling scores with IQ covaried out. Both groups with and without RD could be differentiated from a control group on laboratory measures of sustained attention and impulse control. Methylphenidate benefited all subgroups equally, whether RD or not, and whether given a low (0.3 mg/kg) or high (0.6 mg/kg) dose.     

Identifying dyslexia in multilingual students: can phonological awareness be assessed in the majority language?

A study of 97 students from two schools in Göteborg, Sweden, examined reading proficiency and phonological skill using a comprehensive battery of group measures in the classroom. The sample comprised 38 monolingual native‐Swedish speakers, and 59 multilingual students for whom Swedish is an additional language. Students were administered tests of non‐verbal intelligence, vocabulary, reading comprehension, word recognition and non‐vocal phonological tasks. Two sub‐groups of 26 monolingual and 26 multilingual students, matched on non‐verbal intelligence, also participated in oral word and nonword reading tasks. No significant differences were found between language groups on the separate phonological subtests or the composite phonological score after controlling for non‐verbal intelligence in hierarchical regression analyses. The language groups were equally represented at the 20th percentile on both composite phonology and word reading measures. The composite phonological score was equally powerful for both language groups in predicting word recognition. The results of the present study suggest that, given sufficient exposure to the majority language, it is possible to assess a range of phonological skills among speakers of minority languages using the same battery of tasks as for native speakers.     

Reading research for students with LD: a meta-analysis of intervention outcomes

The present article provides a meta-analysis of instructional research with samples of children and adolescents with learning disabilities in the domains of word recognition and reading comprehension. The results of the synthesis showed that a prototypical intervention study has an effect size (ES) of .59 for word recognition and .72 for reading comprehension. Four important findings emerged from the synthesis: (a) Effect sizes for measures of comprehension were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies included direct instruction; (b) effect sizes related to reading comprehension were more susceptible to methodological variation than studies of word recognition; (c) the magnitude of ES for word recognition studies was significantly related to samples defined by cutoff scores (IQ > 85 and reading < 25th percentile), whereas the magnitude of ES for reading comprehension studies was sensitive to discrepancies between IQ and reading when compared to competing definitional criteria; and (d) instructional components related to word segmentation did not enter significantly into a weighted least square hierarchical regression analysis for predicting ES estimates of word recognition beyond an instructional core model, whereas small-group interactive instruction and strategy cuing contributed significant variance beyond a core model to ES estimates of reading comprehension. Implications related to definition and instructional components that optimize the magnitude of outcomes are discussed.     

ADHD and reading disability in male adults: is there a connection?

The present study examined the comorbidity between attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) in male adults. Participants were 120 men, of whom 24 were classified as having ADHD. The basis for the diagnosis was two self-report scales validated by interviews and background data. An extensive battery was used to assess phonological abilities and various aspects of reading skills. No differences were obtained between adults with and without ADHD on measures of either phonological processing skills or word decoding, indicating a low comorbidity with RD. This finding was valid even when different criteria were used to diagnose RD. However, the two groups differed in reading comprehension, with individuals with ADHD performing poorly in tests of reading comprehension. These results are compatible with the view that reading comprehension involves many of the higher cognitive control functions assumed to be impaired in ADHD. However, these attentional control functions are not critical to word recognition, which is determined by a more encapsulated phonological processing module. The pattern of associations between ADHD and RD observed in the present study is explained with reference to the differential attentional demands of the two aspects of reading.     

Linguistic profiles of dyslexic and good readers

Linguistic profiles of 60 boys with average intelligence were examined at kindergarten, grade 2, and grade 4. The subjects were 7 dyslexic, 7 mildly dyslexic, 30 average, and 16 good readers, defined in terms of the discrepancy between standardized reading and intelligence scores. Across the three ages, reader groups did not differ in language comprehension, but did differ in confrontation and rapid automatized naming (RAN), three syntactic measures, and verbal memory. Group strengths and weaknesses were, with few exceptions apparent in kindergarten and maintained throughout. The kindergarten tasks which most effectively predicted reading group membership at grade 4 were giving letter sounds, and rapid naming; these predicted 4th grade reading group at close to 100 percent accuracy. The study, together with a further comparison of average and high IQ good readers, provides an interesting contrast between the role of RAN and Confrontation naming in reading. This work was supported in part by NIHCD grants RO1HD18761 to F. H. Duffy, RO1HD18654 to H. Als, and the Mental Retardation Grant P30HD18655 to C. F. Barlow.     

Beyond phonological skills: broader language skills contribute to the development of reading

This paper reports a study that followed the development of reading skills in 72 children from the age of 8.5 to 13 years. Each child was administered tests of reading, oral language, phonological skills and nonverbal ability at time 1 and their performance on tests of reading comprehension, word recognition, nonword decoding and exception word reading was assessed at time 2. In addition to phonological skills, three measures of non‐phonological oral language tapping vocabulary knowledge and listening comprehension were unique concurrent predictors of both reading comprehension and word recognition at time 1. Importantly, all three measures of oral language skill also contributed unique variance to individual differences in reading comprehension, word recognition and exception word reading four and a half years later, even when the autoregressive effects of early reading skill were controlled. Moreover, the extent to which a child's word recognition departed from the level predicted from their decoding ability correlated with their oral language skills. These findings suggest that children's oral language proficiency, as well as their phonological skills, influences the course of reading development.     

Does Set for Variability Mediate the Influence of Vocabulary Knowledge on the Development of Word Recognition Skills?

This study investigated the hypothesis that vocabulary influences word recognition skills indirectly through set for variability, the ability to determine the correct pronunciation of approximations to spoken English words. One hundred forty children participating in a 3-year longitudinal study were administered reading and reading-related measures at four time points. Hierarchical regression and path analyses indicated that vocabulary and phonemic awareness made independent contributions to variance in set for variability; that vocabulary directly influenced future reading comprehension and indirectly influenced future decoding and word recognition through set for variability; and that set for variability influenced future reading comprehension indirectly through both decoding and word recognition, controlling for autoregressive effects.     

Effects of Ritalin on Academic Achievement from First to Fifth Grade

This study was a continuation of the Alto and Frankenberger (1995) study that reported the effects of Ritalin on academic achievement from first to second grade. The objectives of the current study were to identify the long-term effects of Ritalin on cognitive ability and academic achievement. A retrospective/longitudinal design was utilised in the study with dependent measures being scores from the Iowa Test of Basic Skills (ITBS). The study included 13 experimental subjects who were identified with AD/HD and placed on Ritalin between first and second grade. For each experimental child, a contrast child without AD/HD was matched based on gender, Verbal IQ score, and family structure. Results of the study revealed that generally, the Ritalin group's cognitive and achievement scores were lower before medication and the groups tended to continue to diverge after medication was administered. Dosage levels for the children in the Ritalin group tended to be increased over time and few of the children in general education classes received supplementary educational programs.     

The development of reading comprehension skills in children learning English as a second language

Reading comprehension is a multi-dimensional process that includes the reader, the text, and factors associated with the activity of reading. Most research and theories of comprehension are based primarily on research conducted with monolingual English speakers (L1). The present study was designed to investigate the cognitive and linguistic factors that have an influence on reading comprehension in English-as-a-Second-Language (ESL) speakers. The cognitive aspects of reading comprehension among L1 speakers and ESL speakers in the seventh grade were investigated. The performance of both groups was compared and the role of some relevant processes, including word reading, word reading fluency, phonological awareness, working memory, and morphological and syntactic awareness were assessed. Within this sample, three groups were examined: (1) children with poor comprehension (PC) in the absence of word reading difficulties (2) children with poor word reading and poor comprehension (poor readers, PR) (3) and children with both good word reading and comprehension abilities (good comprehenders, GC). The results demonstrated that a variety of cognitive processes, such as working memory and phonological, syntactic, and morphological awareness are important for reading comprehension and compromised in poor comprehenders. The GC group performed better than the PC group on all of the cognitive measures, indicating that comprehension depends on a variety of phonological, memory and linguistic processes and that adequate word recognition skill are important for reading comprehension. The prevalence of the ESL and L1 students was similar across the three reading groups. The ESL and L1 students demonstrated similar performance, indicating that the skills underlying reading comprehension are similar in the ESL and L1 students. This study demonstrated that ESL students are capable of developing word reading and reading comprehension skills that are as strong as those of their L1 peers.     

The use of computer-automated reading in reading instruction

This study evaluates the use of computer-automated reading in reading instruction and illustrates a resource role for school psychologists in providing consultative assistance for computer-assisted instruction. A reading specialist serving as the teacher's aide was taught to write computer programs for automated reading on a personal computer with a speech synthesizer. The teacher selected six beginning-reading books for her remedial reading classes with 1st- and 2nd-grade students. Five 1st-grade and five 2nd-grade students, enrolled in a compensatory education program, were randomly assigned to two experimental groups; five 1st-grade and five 2nd-grade students, enrolled in the same program, were randomly assigned to two control groups. The students in the experimental groups received automated reading with their instruction; the students in the control groups received instruction in the same books, without automated reading. Pre- and posttests of word recognition, phrase reading, and reading comprehension were administered. The random selection of 1st-grade students failed to yield comparable groups, and the contrast of adjusted posttest scores was nonsignificant. Analyses of covariance on the reading criteria for the 2nd-grade groups indicated significant achievement gains for the experimental group.     

The effects of oral repeated reading with and without corrective feedback on middle school struggling readers

This study examines the effects of oral repeated reading, with and without corrective feedback, on the fluency and comprehension skills of 60 struggling readers in 7th Grade. Comparisons were made by group on narrative and expository reading ability and by comprehension question type. Students were randomly assigned to one of two reading groups (oral repeated reading with corrective feedback and oral repeated reading without corrective feedback). Participants in each group were required to repeatedly read a narrative and an expository passage. Statistical analyses (namely, repeated measures ANOVA and ANCOVA) were used to determine the overall effects on fluency and comprehension and differential effects demonstrated by groups on text type and comprehension question type. Results indicated that both forms of intervention improved fluency and comprehension. Limitations and implications for research and practice are discussed.     

An investigation of reading and language abilities of college freshmen

The purpose of this study was to compare a range of reading–related abilities in two groups of college freshmen with higher and lower reading comprehension abilities. Reading comprehension ability groups were formed using American College Test reading scores. The groups were compared on measures of oral language vocabulary and syntax, phonemic awareness and print decoding skills. Results indicated that abilities that appear to relate to reading comprehension include recognition of the order of phonemes in spoken syllables, recognition of words that are good semantic and syntactic fits for sentence frames, recall of meanings for spoken words and conversion of printed to spoken words.     

The Relation between Reading Comprehension and Task‐specific Strategies used in Arithmetical Word Problems

The study was concerned with the relation between reading comprehension and task‐specific strategies used in arithmetical word problems. Two hypotheses were formulated in the study. H1 stated that subjects good at arithmetic as well as reading (Group 1) would emphasize deductive strategies to a greater extent than subjects in the remaining groups. H2 considered IQ to be a stronger predictor for subjects’ strategies in arithmetical word tasks than reading comprehension. Four groups of 9‐year‐old children with different competencies in arithmetic and reading were sampled for the investigation. An intelligence test (WISC) and three other tests, Mathematical tests 1‐3, were constructed and administered to the 20 subjects. The tests were used to examine subjects’ strategies in completed task solutions. The findings indicated that great similarities existed between Groups 1 (good at both skills) and 2 (good at arithmetic and poor at reading) as to strategies used in addition and subtraction problems. Whereas subjects in groups 1 and 2 mainly used deductive strategies, those in Groups 3 (good at reading and poor at arithmetic) and 4 (poor at both skills) rather used procedural strategies in solving the problems. Concerning strategies applied in multiplication and division tasks a more diverse pattern of strategies was revealed in all of the four groups, but the majority of subjects emphasized deductive strategies. Multiple regression analyses of the data indicated strong linear relationships between the predictors and the criteria used in the analyses. However, IQ was the only significant single predictor found in the regression analyses. H1 had to be suspended, but H2 could not be rejected.     

Investigating Cognitive and Linguistic Abilities that Influence the Reading Comprehension Skills of Children from Diverse Linguistic Backgrounds

This study investigated the influence of cognitive and linguistic skills on the reading comprehension performance of a group of learners from diverse linguistic backgrounds. The study also compared the reading comprehension performance of grade 4 children who entered kindergarten with little or no experience with English (ESL) to that of a group of native English speakers. Examiners administered various tasks of reading, language, and memory to the children in the study (n=480). The sample included three comprehension groups: (1) children with poor comprehension in the absence of word reading difficulties (Poor Comprehenders; PC), (2) children with poor word reading and poor comprehension (Poor word Recognition and comprehenders; PR), and (3) children with good word reading and comprehension abilities (Good Comprehenders; GC). Due to the small sample size of PR reader group, no comparative analyses were conducted. However, the results indicated that within the GC and PC groups there were no differences between the ESL and L1 children on measures of reading and phonological processing. Further, within the GC and PC groups, on measures of syntactic awareness and verbal working memory, the ESL speakers performed at significantly lower levels than the L1 speakers.
